It does nothing. Valid option letters are [acCdghrsv].

All which man pages?

The loader "boot" command means "boot immediately", as documented in
the help. The "autoboot" command means "boot after a delay", as
documented in the help. They're mutually exclusive, so you're right:

boot2:
/boot.config
loader:
/boot/loader.rc
/boot/defaults/loader.conf
/boot/loader.conf
/boot/loader.conf.local
kernel:
/boot/kernel.conf

Yes.
